The Duplicate Sidebar Widget allows for easy duplication of another sidebar's widgets simply by dropping in the Duplicate Sidebar widget and selecting the sidebar to be duplicated from the drop-down.

The Widget Content feature adds the use of an advanced editor to create widget content. A new Widget Content top-level menu is now on the back-end and allows for creation of widget content with the same interface as posts and pages. Once a Widget Content entry is saved, you can add the Widget Content widget to a sidebar location and select the desired Widget Content entry from the drop down to add that content to a sidebar.
